Dialysis01:15

Dialysis

583
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

779
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Methods for Studying Drug Absorption: In situ

201
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

98
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

473
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...

Methods for Studying Drug Absorption: In vitro01:16

Methods for Studying Drug Absorption: In vitro

199
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

Area of Science:

  • Nephrology
  • Biomedical Engineering
  • Pharmacology

Background:

  • Peritoneal dialysis (PD) solutions manage uremic toxins, sodium, and water.
  • A novel intraperitoneal (IP) solution of icodextrin and glucose, without uremic toxin clearance, may enhance sodium and water removal.

Purpose of the Study:

  • To evaluate a 30% icodextrin and 10% dextrose IP solution for enhanced sodium and water removal.
  • To assess the safety and efficacy of this novel IP solution in animal models and humans.

Main Methods:

  • Varying concentrations of icodextrin and dextrose IP solutions were examined in rats.
  • A 30% icodextrin and 10% dextrose IP solution was evaluated in small and large animal models and 10 human participants with kidney failure.
  • Outcomes included ultrafiltration (UF), sodium removal, peritoneal health, safety, and tolerability.

Main Results:

  • Increasing icodextrin and dextrose concentrations in rats led to greater UF.
  • In sheep, the 30% icodextrin and 10% dextrose solution showed significantly higher UF (3.5-fold) and sodium removal (4-fold) compared to standard 7.5% icodextrin PD solution.
  • Long-term animal studies revealed no significant tissue damage. Human trials showed substantial UF and sodium removal with no serious adverse events.

Conclusions:

  • A 30% icodextrin and 10% dextrose IP solution offers more efficient UF and sodium removal than conventional PD solutions.
  • Promising human safety and efficacy data support further investigation for treating edematous disorders like heart failure.
